In which of the following ionic radii of chromium would

A

`K_2CrO_4`

B

`CrO_2`

C

`CrCl_3`

D

`CrF_2`

Text Solution

Verified by Experts

The correct Answer is:
A
Oxidation number of Cr in options a, b, c and d are +6, +4, +3, +3 respectively.
In given options (a) has high oxidation number therefore its radii will be low. Atomic radii decreases with increase in oxidation no.
